Hi, I just thought of sharing this plugin to you guys for you might find it useful as well.
This plugin automatically adds rel="nofollow" to all external links in your wp website (you can add exceptions in the plugin page).
This plugin will not remove old rel of a link (if any), but this plugin smartly adds necessary rel attributes. For addition this plugin can remove links on comments too.
Tested on Wordpress 3.2
Enjoy! (y)
